NON-DESTRUCTIVE TESTING

COMMITMENT TO QUALITY IS OUR GOAL

Nondestructive testing performed on materials and parts at TAG

SERVICE

Non-destructive testing (NDT) is used to detect both internal damage mechanisms and cracks on the surface of parts without causing geometrical or resistance changes in the material. Each inspection process provides a detailed list of the features of the detected defects, determining whether or not the part is fit for a desired function.

STANDARD

At TAG competency in carrying out NDT tasks is paramount in order to make sure quality and safety standards are met. Thus our skilled personnel is qualified at NDT Level II and III under EN ISO 9712 – EN 4179 NAS 410. Moreover, our Liquid Penetrant Testing achieved Nadcap accreditation in December 2014.

VALUE

When it comes to non-destructive testing performed on special types of superalloyed gas turbines, as well as on aerospace components made of light alloys, titanium alloys and PH stainless steel, at TAG we use a semi-automatic system with immersion / spray tanks with water-washable and post-emulsifiable penetrant liquids at sensitivity level 3 qualified under AMS 2644.

OUR METHOD

We offer a broad range of NDT inspection services

Using a comprehensive range of cutting-edge technologies, our NDT testing methods cater for the detection of even extremely small surface cracks. Moreover, ultrasonic techniques are used to detect internal flows deep in the part, as well as to measure the remaining wall thickness of structures.

NDT INSPECTION METHODS

Liquid penetrant testing (Fluorescent Penetrant Inspection – FPI);

Ultrasonic Testing (UT);

Eddy-current Testing (ET);

Visual Testing (VT);

Magnetic Particle Inspection (MPI).

SPECIAL TECHNIQUES

At TAG we use the Eddy Current testing technique to perform electrical conductivity measurements in order to characterize, among others, the properties of materials after heat treatments. The internal channels or deep holes of parts are instead checked via video endoscopes able to acquire images and video material.
